Filed Get. 31, 1953, Ser. No. '77@,995 3 Claims. (Cl. S12-195) The present invention relates to furniture construction and refers more particularly to a desk of metal frame pedestal construction having paneling secured to the metal frame with tongue and groove joints which desk may be quickly and easily assembled or disassembled.

Furniture made entirely of material such as wood has less strength than furniture having a metal frame and is subject to deterioration at exposed corners. Furniture made entirely of metal does not have the richness and Warmth of softer, more decorative, materials. Therefore there is a need for furniture having a strong metal frame and metal corners which furniture retains the richness and warmth of decorative material such as wood.

In the past furniture constructed of a combination of decorative material and metal has in general been unsatisfactory. The connections between the members of such furniture have been more or less exposed and ugly. Maintenance and repair on such furniture has often been poor and expensive due to the inexperience of metal workers in treating decorative materials and decorative materials Workers in repairing metal. Furthermore the manufacture of furniture using a combination of materials has presented problems due to the need for different tools and technologies within a single manufacturing unit for the different materials used.

l Also, shipping and storage of articles of furniture has been expensive and diiiicult due to the bulk of an assembled unit. Furthermore maintenance previously was complicated on furniture due to the substantially permanent character of the connections between the elements thereof.

Therefore it is one of the essential objects of this invention to provide an article of furniture having exposed metal frame and decorative paneling which is so constructed that connections between the wood and metal elements are not visible.

Another object is to provide an article of furniture having a metal frame and Wood panels connected by means of tongue and groove joints.

Another object is to provide an article of furniture having a metal frame with tongues extending therefrom and having paneling with a groove in the edge thereof, the frame and paneling being secured together with a tongue and groove joint.

Another object is to provide an article of furniture having a metal frame and decorative panels which may be easily separated for maintenance purposes.

Another object is to provide an article of furniture which is capable of easy disassembly and packaging for shipment or storage in a compact package unit.

Another object is to provide an article of furniture having a metal frame and wood paneling which is simple in construction, easy to produce and eiiicient in use.

Other objects, advantages and novel details of construction of this invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings, wherein:

The embodiment of the invention shown in the drawings is a desk generally designated 2 in FIGURES l, 2 and 3. The desk as illustrated includes a metal frame 4 having tongues 6 on individual frame members, panels 8 with grooves 10 in the edge thereof and a top 12. Panels 8 are 'positioned in frame 4 with the tongue 6 inserted in grooves 10. The top 12 is then attached to frame 4. Such construction is simple and eicient producing a desk with the strength of metal where it is needed and having lthe warmth of wood without exposed connections.

Frame 4 includes four vertical corner posts 14, 16, 18 and Ztl fixed in rectangular relation by horizontal members 22 and 24 on the sides of the desk and front horizontal member 26 all rigidly connected to the corner posts as shown in FIGURE 5 by brackets 27 and screws 28 and 29. Shorter horizontal frame members 30 and 31 are` provided at the back of desk 2 extending toward each other from corner posts 14 and 16 as indicated in FIG- URE l. vided in the front of desk 2 extending vertically from the top of front horizontal member 26 as shown in FIGURE 2. Intermediate vertical posts 36 and 38 are provided in the back of desk 2 extending vertically from the ends of horizontal members 30 and 31 which are furthest from corner posts 14 and 16 respectively as shown in FIGURE l. Horizontal members 40 and 42 are also provided extending between the intersections of front horizontal member 26 and intermediate vertical posts 32 and 34 and the intersections of short horizontal members 30 and 31 with intermediate vertical posts 36 and 38 respectively. Members 40 and 42 are parallel to and in the plane of horizontal members 22, 24, 26, 30 and 31.

All members of the frame described are of generally rectangular cross section having tongues 6 extendingl from selected sides thereof as indicated in FIGURES 4-6 and 8-l0. Tongues 6 extend for substantially the full length of the members on the sides indicated in the figures and are provided for the purpose of forming a tongue and groove joint between frame 4 and panels 8.

Bracket 27 as shown in FIGURE 5 is provided at each interior corner for the purpose of connecting the horizontal and vertical members of frame 4. A at area 43 is machined in the vertical corner members as shown in FIGURE 5 so that a hole may be drilled and tapped therein for connection of screw 2S as shown. Portions of the horizontal members, as shown at 44 and 45 in FIGURE 5 are cut away Where corners are formed therebetween to allow screw 28 to be inserted between bracket 27 and the vertical members.

Frame 4 is made of metal to provide strength for desk 2 and to protect the edges and corners of the desk from Stainless steel, steel or aluminum are possible materials from which the frame may be constructed. The individual members may be extruded to shape or built up of other forms.

Panels 3 may be of wood, Wood with aluminum surfacing, formica or other suitable material colored or tex- Intermediate vertical posts 32 and 34 are pro-.

tured as desired. The panels 8 have grooves 10 in the edges thereof as shown in FIGURE 8. Panels 8 may be manufactured in any known manner and in assembly are inserted from the top into frame 4 between adjacent vertical posts. Tongues 6 on frame 4 fit within grooves 10 in panels 8. Panels 8 rest on the horizontal members 22, 24, 26, 30 and 31 and are held securely in place by tongues 6 in tongue and groove joints as indicated. Vertical walls for desk 2 are thereby produced which may have the warmth of wood and which may be easily detached from the metal frame for maintenance. Assembly of the panels 8 in frame 4 is simple and allows the frame 4 and panel 8 to be produced in widely separated places and to be assembled after linishing operations have been completed on both the panels and the frames.

Top 12 includes a rectangular metal frame 46 including members 47, 48, 49, and 50 similar to the members of frame 4 and of a cross section shown in FIGURES 6 and 8 including tongues 6. A desk top panel 51 of any desired material or size may be attached to the upper surface 52 of frame 46 by clips 53 and screws 54 as shown in FIGURES 6 and 8. Frame 46 is attached to the upper ends of the intermediate vertical posts of frame 4 in the manner indicated in FIGURE 7 by means of countersunk clearance holes 55 in frame 46, holes 56 tapped and drilled in the end surface of the intermediate vertical frame members and cap screws 57.

In manufacture frame 4 is finished and assembled by means of brackets 27. Panels 8 are produced, nished and inserted in frame 4, being held in place by the tongue and groove joint described previously. Rectangular frame 46 is constructed, finished and attached to frame 4 locking panels 8 in place with easily removable nonvisible connections. Top panel 51 is made and attached to frame 46 asy shown in FIGURE 8 thereby completing an article of furniture according to the invention having the advantage of both wood and metal desks and being simple to construct and maintain.

Furthermore it will be noted that with the construction and connections as described herein using tongue and groove joints and assembly brackets, screws and bolts, it is,y possible to completely dismantle the furniture construction for shipping or storage in a compact flat unit.

Drawers 58 may be provided in the back of desk 2 in place of panels 8 if so desired. The drawers if provided may be suspended from panels 8 which are crosswise of the desk 2 by means of spacers, rollers and tracks, all of which are conventional and are therefore not shown.

A dust board 60 may also be provided' at either end of desk 2. The dust board may be supported to tongues 6 extending from members 22, 24, 26, 28, 30, 40 and 42 in the manner illustrated in FIGURE 4.

While a specific embodiment of the invention herein disclosed has been described, it will be obvious to one skilled in the art that many modifications and applications of the invention are possible. Wall partitions, store tixtures, waste baskets and tables are only a few of the many articles that may be constructed according to the invention. Therefore applicant does not wish to be limited to the specific embodiment of the invention disclosed herein.
